GM Ophelia at your service.
We are aware of the issue where accounts linked to Facebook cannot login to the game due to the Facebook login authentication issues. We apologize for the inconvenience caused to the Raiders logging in through Facebook, and we will do our best to resolve the issue as soon as possible.
Unfortunately, we ask for your understanding that it may be difficult to solve the issue within today as the issue must be worked with Facebook.
We will notify the Raiders as soon as the issue is resolved.
